Abstract :
In this paper, a new power factor measurement method is proposed. The proposed method is implemented by an analog electronic circuit. Its response time is less than a half-cycle. The test results show that it can measure the power factor of the measured load quickly and accurately, and its response time is superior to the conventional power factor measurement methods
